Example: Intermodulation spectrum measurement in a new channel.
*RST; FREQ:IMOD:LTON PORT,1; UTON GEN, 1
Reset the instrument to create the default channel no. 1. Select
port 1 as a source port for the lower tone, a (previously config-
ured) external generator no. 1 as a source port for the upper
tone.
FREQ:STAR 1GHZ; STOP 2GHz
Define a suitable sweep range to ensure that the analyzer can
measure all intermodulation products.
CALC2:PAR:SDEF 'Trc2', 'S21'
Create a new channel no. 2 and a trace named 'Trc2'. Select S
21
as a measured quantity.
DISP:WIND:TRAC2:FEED 'Trc2'
Display the new trace in diagram no. 1.
SENS2:FREQ:IMOD:SPEC ON
Enable the intermodulation spectrum measurement for the new
channel no. 2.
CALC2:PAR:CAT?
Query the traces in channel no. 2. The response is
'Trc2,B2D1SAM'.
Manual operation:
See "CW Mode Spectrum" on page 336
[SENSe<Ch>:]FREQuency:IMODulation:TDIStance <ToneDistance>
Defines the tone distance (frequency offset) between the upper and the lower tone.
Suffix:
<Ch>
.
Channel number
Parameters:
<ToneDistance> Upper tone frequency minus lower tone frequency.
Range: Lower limit: 0 Hz, upper limit depending on the
instrument model and the sweep range for the
lower tone.
*RST: 1 MHz
Default unit: Hz
Example: See [SENSe<Ch>:]FREQuency:IMODulation:LTONe
Manual operation: See "Delta Frequency" on page 341
[SENSe<Ch>:]FREQuency:IMODulation:UTONe <SourceType>[, <arg1>]
Selects the source for the upper tone signal that is used for the intermodulation mea-
surement.
Suffix:
<Ch>
.
Channel number
Parameters:
<SourceType> PORT | GENerator | NONE
